Localizations for quiver Hecke algebras

Abstract

We provide the localization procedure for monoidal categories by a real commuting family of braiders. For an element ww of the Weyl group, Cw\mathscr{C}_w is a subcategory of modules over quiver Hecke algebra which categorifies the quantum unipotent coordinate algebra Aq[n(w)]A_q[\mathfrak{n}(w)]. We construct the localization Cw~\widetilde{\mathscr{C}_w} of Cw\mathscr{C}_w by adding the inverses of simple modules which correspond to the frozen variables in the quantum cluster algebra Aq[n(w)]A_q[\mathfrak{n}(w)]. The localization Cw~\widetilde{\mathscr{C}_w} is left rigid and we expect that it is rigid.
